# Seconds Of Arc to Milliradians Conversion

Enter the angle in seconds of arc below to get the value converted to milliradians. ## How to Convert Seconds Of Arc to Milliradians To convert a second of arc measurement to a milliradian measurement, multiply the angle by the conversion ratio.

Since one second of arc is equal to 0.004848 milliradians, you can use this simple formula to convert:

milliradians = seconds of arc × 0.004848

The angle in milliradians is equal to the seconds of arc multiplied by 0.004848.

For example, here's how to convert 500 seconds of arc to milliradians using the formula above.
500" = (500 × 0.004848) = 2.424068 mrad

## Seconds Of Arc

The second of arc is a unit of angle equal to 1/60th of one minute of arc or 1/3,600 of one degree.

A second of arc is sometimes also referred to as an arc second or arcsecond. Seconds of arc can be abbreviated as arcsec, and are also sometimes abbreviated as asec. For example, 1 second of arc can be written as 1 arcsec or 1 asec.

The second of arc is most commonly expressed using a double prime (″), though a double quote is often used as well. For example, 1 second of arc is most often written as 1″.

A milliradian is equal to 1/1,000 of a radian. One degree is equal to 0.0573 milliradians and there are 6,283 milliradians in a full revolution/circle. The milliradian is also a commonly used unit in mathematics.

The milliradian is a multiple of the radian, which is the SI derived unit for angle. In the metric system, "milli" is the prefix for 10-3. A milliradian is sometimes also referred to as a mil. Milliradians can be abbreviated as mrad; for example, 1 milliradian can be written as 1 mrad.
